What is the OUI A0:86:EC?

A0:86:EC is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to SAEHAN HITEC Co., Ltd. It covers every address from A0:86:EC:00:00:00 to A0:86:EC:FF:FF:FF, or 16,777,216 addresses in total. It is also written A0-86-EC.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in A0:86:EC:00:00:00 that is A0:86:EC — and look that prefix up in the IEEE OUI registry. If the second-lowest bit of the first octet is set, the address is locally administered (a randomized or private MAC), which belongs to no manufacturer and will not resolve; modern phones and laptops use these by default on each network.

Where is SAEHAN HITEC Co., Ltd located?
